textView 添加超链接(两种实现方式)

public class MainActivity extends Activity { 
@Override 
protected void onCreate(Bundle savedInstanceState) { 
super.onCreate(savedInstanceState); 
LinearLayout layout = new LinearLayout(this); 
LayoutParams params = new LayoutParams(LayoutParams.MATCH_PARENT, 
LayoutParams.MATCH_PARENT); 
TextView textView = new TextView(this); 
String html = "有问题：\n"; 
html+="<a href=‘http://www.baidu.com‘>百度一下</a>";//注意这里必须加上协议号，即http://。 

//否则，系统会以为该链接是activity，而实际这个activity不存在，程序就崩溃。 
CharSequence charSequence = Html.fromHtml(html); 

textView.setText(charSequence); 

textView.setMovementMethod(LinkMovementMethod.getInstance()); 
layout.addView(textView); 
this.setContentView(layout,params); 
} 

public class MainActivity extends Activity {

LayoutParams params = new LayoutParams(LayoutParams.MATCH_PARENT, 
LayoutParams.MATCH_PARENT); 
TextView textView = new TextView(this); 
String html = "有问题：\n"; 
html+="www.baidu.com";//这里即使不加协议好HTTP；也能自动被系统识别出来。 
textView.setText(html); 
textView.setAutoLinkMask(Linkify.ALL); 
textView.setMovementMethod(LinkMovementMethod.getInstance()); 
layout.addView(textView); 
this.setContentView(layout,params);
